PhaseListener in JSF ... Einrichtung nicht möglich

Hi,
lange her dass ich hier mal vorbeigeschaut habe. Aber jetzt habe ich ein Problem bei dem ich nicht weiter komme.
Ich versuche für ein Projekt einen PhaseListener zu implementieren. Doch zuerstmal die Rahmendaten:
Server: JBoss 4.2.3 GA
JSF mit richFaces 3.2.2 GA

Der Faces-Config ausschnitt sieht wie folgt aus:
HTML: 
<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="1.2" xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:xi="http://www.w3.org/2001/XInclude"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd">
 
 <!-- 
 Es gibt Probleme den PhaseListener zu registrieren,
 wenn dieser Registriert wird,
 gibt es eine ConfigurationException.
 -->
 <lifecycle>
 	
 	<phase-listener>de.meine_energie.view.init.PortalPhaseListener</phase-listener>
 </lifecycle>

  <managed-bean-scope>session</managed-bean-scope>
 </managed-bean>
...
 <navigation-rule>
 	<display-name>sites/user/update_step3</display-name>
 	<from-view-id>/sites/user/update_step3.jsp</from-view-id>
 	<navigation-case>
 		<from-outcome>back</from-outcome>
 		<to-view-id>/sites/user/update_step2.jsp</to-view-id>
 	</navigation-case>
 </navigation-rule>
 ...

sieht ja alles normal aus ... auch die Klasse de.meine_energie.view.init.PortalPhaseListener existiert und sieht folgendermaßen aus:
Java: 
package de.meine_energie.view.init;

import javax.faces.event.PhaseEvent;
import javax.faces.event.PhaseId;
import javax.faces.event.PhaseListener;

public class PortalPhaseListener implements PhaseListener {

	public void afterPhase(PhaseEvent arg0) {
		// TODO Auto-generated method stub

	}

	public void beforePhase(PhaseEvent event) {
//		if(event.getPhaseId()==PhaseId.RESTORE_VIEW){
//			if(event.getFacesContext().getExternalContext().getSession(false)==null){
//				
//				event.getFacesContext().getApplication().getNavigationHandler().handleNavigation(event.getFacesContext(), "", "sessionExpired");
//			}
//		}
		System.out.println("PHASE: "+event.getPhaseId());

	}

	public PhaseId getPhaseId() {
		// TODO Auto-generated method stub
		return null;
	}

}

und nun natürlich noch die Exception:

10:00:21,202 ERROR [StandardContext] Error listenerStart


alle Dateien werden per ant zusammengepackt (in ein WAR-File und dann in ein EAR-File) und auf den JBoss geschoben.
Jedoch kann ich mir nicht erklären warum er eine NullpointerException bekommt.

Hat da jemand von euch vielleicht einen einfachen Rat?

Hi Robert,

ich habe das gleiche (ähnliche) Problem mit JSF/Portlet/WebSphere.
Seit ich einen PhaseListener in die faces-config.xml eingetragen habe, scheppert es beim Hochfahren von JSF:

Die Lösung ist:
Der PhaseListener hat bei der Initialisierung eine Exception geworfen. Daher die Fehlermeldung...

Gruß
Andreas
 
Hm, der Thread ist uralt, aber ich habe ihn ja auch noch gefunden ;-) Zum Ausgangspost: Die PhaseId muss gesetzt werden, z. B. auf ANY_PHASE:

public PhaseId getPhaseId() {
return PhaseId.ANY_PHASE;
}

Die Klasse PhaseId hat statische Werte für alle existierenden Phasen sowie die Wildcard für jede Phase.
